Re: GT2-A frame
I have a GT2a and a GT2a-s. I like them both and recommend either one. The frame tubes are larger diameter than the motor mounts though. The "a" frame has a T shaped front motor mount, but an adaptor is needed for the rear mount. The "s" frame has no front motor mount and an adaptor will be needed for both front and rear mounts. I modified both front and rear mounts to direct mount the engine to the "s" frame with no adaptors. Much stronger and smoother.... Now here is the really good news. You find all the mounts, clamps, adaptors, and brackets that you will need for your new GT2 frame at bikebobber.com. Check out Bike Bobber on Facebook too.
